Wind noise and water ingress with an automotive oscilloscope and Noise, Vibration and Harshness NVH

[@martinrubenstein7943]

How clever, Steve. It’s the audio equivalent of a smoke machine. What a smart way to track down water ingress. These case studies are also an excellent way to demonstrate the practical use of the NVH software - much more meaningful than talking through the features in an abstract way with no specific purpose in mind. And it’s surprisingly sensitive, too; even if you weren’t aiming not to irritate bystanders, I guess you’d want to use such a high frequency because you probably wouldn’t get the same sensitivity at lower frequencies. It’s very impressive, if not ingenious. I for one would be happy to watch more of the same. Thanks, Steve.

Really interesting that thanks Steve cant wait to try it out in the workshop.

Hello. Very interesting measurement indeed. Of course, there are some factors that can have some influence on your measurements. I bet that the car used for your example has the tweeters (which outputs the 15kHz frequency) right next to the side mirrors. But still a useful test. Thank you!

When will the NVH Kit be available? Has been showing out of stock for a long time when I have checked.

[@yankkesrule]

Heard from pico year ago they didn’t expect to have stock for two years

A passenger with a couple feet of hose or tubing can find a wind leak... Just sayin'.

Yes .. but this is far more fun ! and carry's a higher diagnostic fee
